I am a sour cream fanatic -- to the point where my gravestone is likely to read "'Twas the butterfat that did him in"
I like all variations of it: Mexican crema, creme fraiche, even the low-fat versions (no, not the non-fat stuff).
So I needed some Creme Fraiche for a recipe for New Year's Eve, and local stores didn't seem to carry it*. From previous notes I'd seen, I could expect to pay $5 and up for a small jar too. So I made my own:
Hardware: Clean mason jar, plastic lid, plastic wrap, spoon, freezer
Software: 1.25C Heavy Cream (a quart we'd picked up from Costco the other day), 1Tbs Buttermilk (ordinary Dean's)
Put the cream in the jar and microwave for 30 seconds to warm it slightly. Add the buttermilk, and cover loosely with plastic wrap so it can breathe
Put the jar on the counter next to the freezer coils, where it's a little warmer. Periodically swirl the jar or stir it up, until it thickens.
In less than 24 hours, I had lightly sour, slightly nutty cream, about as thick as mexican crema (pourable with patience).
Now, I just have to restrain myself from devouring it before tomorrow night.
* OK, two of the stores I looked in were Korean groceries, but the other two ought to have had it.
